Cam unit incorporating batten for controlling the reed of weaving looms

Abstract

A cam unit incorporating batten for controlling the reed of a weaving loom wherein the two members which support the double lever rollers and the conjugate discs of a double drive cam are provided in the form of bushings having end portions extending outside of a housing and which end portions are adapted to be selectively secured to rotatable shafts so that the cam unit may be positioned at any desired location relative to the shafts.

What is claimed is: 
     
       1. A loom batten drive comprising, a cam unit for controlling the rotary oscillating movement of a first shaft by a second rotatable shaft extending parallel to the first shaft, said cam unit including first and second lever means which are adapted to be driven by engagement with first and second elements of a double cam, said first and second layer means being carried by said first oscillating shaft and said double cam being carried by said second rotatable shaft, a housing having first and second sections and opposite end walls, two pair of opposing openings formed in said end walls of said housing through which said first and second shafts are extended, said first and second lever means being supported on a first generally cylindrical bushing which is selectively mounted to said first oscillating shaft so as to be substantially enclosed within said housing, said double cam being supported on a second generally cylindrical bushing which is selectively mounted to said second rotatable shaft so as to be substantially enclosed within said housing, each of said first and second bushings having opposite outer end end portions which extend outwardly through said pairs of opposing openings in said end walls, and clamping means for urging said outer end portions of said first and second bushings into secured engagement with said first and second shafts. 
     
     
       2. The cam unit of claim 1 in which each of said outer end portions of each of said first and second bushings include longitudinal slits which permit said outer end portions to be collapsed about said first and second shafts by said clamping means. 
     
     
       3. The cam unit of claim 2 including a plurality of bearing means mounted within said housing, said bearing means being disposed between each of said first and second bushings and said housing.
